Renewed. April 2, 1930.

The object of our joint invention is the 10 ferred embodiment of our invention.

Figure 2 is a bottom plan of the sign with Figures 3 and'4aresections on the lines 33 and '44, respectively, of Figure 1. a

Figure 5 is a fragmentary section on line 55 of Figure 4. P I Figurefi is a detail section illustrative of the cover hinge.

Figure-7 is 'a perspective view of a. portion. of the cover.

Figure 8 shows one.of the cards on a reducedscale.

Similar numerals-- of reference designate corresponding parts in all of the views of the drawings.

'. Our sign is designed more especially. though not'necess'arily, for the holding and selective display of cards 1 bearing gasolineprices or rates and fractional computations a card-holding body, preferably of sheet metal, in which the cards are removably -ar-,

ranged side by side, Figures 3 and 4. The

.said body is characterized by openings 2 a1 1d 3 in its spaced side walls 4 for the display of cards at opposite sides ofthe device. It is also characterized by'a raised bottom 5 to prevent rain penetrating and settling in the 40 body. At the four corners ofthe bottom 5 are ventilation openings 6, Figure 2, to prevent clouding of the panes of glass 7.

The body is open at the top, Figures 46,

its side walls 4 notched at 9 to facilitate the grasping and removal of the cards 1, is

equipped at one end with a keeper stud 10, Figure 1, and is provided in itsopposite end wall with a slot 11, Figures 4-6.

In association withthe body as described we employ a cover 12, also by preference of sheet metal, marginally flanged at 13 and provided on one, of its end flanges with a' tongue 14, and equipped'at its opposite end with a pendent, resilient latch-strip 15, apertured to receive and engage the stud 10 and thereby detachably secure the cover in closed position, Figure 1. The tongue 14 extends through the slot 11 and'not only hingedly connects the cover to the body, but serves as an abutment for and gauges and holds, thecards 1 against endwise movement, Figure 5, with the result that when the cover is closed all of the cards will-be evened so that the ends threof will be flush and proper positioning of the largefigures and the calculations on the outer card's, relative to the openassured.

Our sign may be mounted 1n any approved prefer,'ho wever, to provide the sign bodyat one end with parallel, apertured lugs 16'and to connect said lugs to sections 17, designed .to be clamped on a gasoline shown.

ings in the side walls 4 of the body, will be manner withoutafi'ectingour invention. We

pump frame not The cover 12 is susceptible of ready removal from the sign body, and with said cover '12 removed, the cards 1 may be expeditiously and easily shifted to bring about the outermost positioning of the cards bearing the desired rate and fractional computations to be displayed. .Then when the cover is replaced and swung to closed and fastened position'on the body, it will be manifest that the tongue 14 by engaging the adjacent end edges of the cards 1 will render all of the cards even and hold the same securely against the remote end wall of the body, Figure 3, for the purpose ,before'indicated.

Having described our invention, what we claim and desire to secure by Letters Patent, 1s: v A v 1.
